LOOSE-LEAF .BOOK- Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed January 31, 1905. Serial No. 243,515.

To all whom it may concern.-

Be it known that I, WILLIAM P. PITT, a citi- Zen of the United States, residing at Independence, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Loose-Leaf Books, of

which the following is a specification.

in the'claims, and in order that it may be terminals of hooks 6.

fully understood reference will now be made to the accompanying drawings, in which Figured represents an end View of the book, partly in section. Fig. 2 represents a resilient retaining-plate, forming part of the invention. Fig. 3 is a perspective view of a pair of hook-carrying members and a tongueplate forming part of the invention. Fig. 4 is adetail perspective view of a portion of the tongue-plate. Fig. 5 is an enlarged transverse section of the book, showing the hooks closed in full lines and open in dotted lines.

In carrying out the invention I employ a cover 1, composed, preferably, of leather and consisting of sides 2, united by a back piece 3.

4 designates a pair of hook-carrying members, to which a plurality of hooks 5 and 6 are secured. Hooks 5 are provided at their upper terminals with V-shaped grooves 7 for the reception of V-shaped tongues 8 on the upper Tongues 8 engage grooves 7 when the hooks 5 and 6 are closed, and thus hold the latter in alinement.

9 designates a retaining-plate, which is slightly arched atits longitudinal central portion 10to render it resilient and provided at its longitudinal sides with marginal flanges 11, which embrace the longitudinal outer edges of the hook-carrying members for the purpose of as'sistingin holding the latter together. Said retaining-plate is provided with transverse open slots 12 forthe reception of the segmental hooks.

13 designates a tongue-plate comprising alternately-arranged tongues 14 15, respec-.

tively, the former of which overlap, while the latter under-lap, the adjacent portions of the hook-carrying members in order to operatively hold them together and cause the adjacent edges of said members to move in unison. Tongues 14 l5-are connected by centrally-disposed webs 16 and flare outwardly (see Figs. 1 and 5) to permit the upward-and-downward movements of the adjacent portions of the hook-carrying members.

The device is secured to the inner surface of the book-back by a strip of tar-board 17, to which plate 9 is secured by rivets 18, extending through holes 9*, marginal recesses .19 in the hook-carrying members, and holes 20 in the tongue-plate.

In assembling the parts the adjacent sides of the hook-carrying members are placed in position between tongues 14 15, as shown in Fig. 3. The retaining-plate 9 is then placed over the hook-carrying members, with slots 12 registering'with hooks 5 6, and expanded so flanges 11 will embrace the outer edges of said hook-carrying members and hold the latter against accidental movement when the hooks thereon occupy an open or closed position. Plate 9 is then secured by rivets 18 to the tar-board, which latter is glued or otherwise secured to the inner surface of back 3.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a device of the character described, hook-carrying members, a resilient member arranged to hold the hooks in an open or closed position, and a member engaging the inner sides of the hook-carrying members.

- 2. In a device of the character described, a plurality. of hook-carrying members adapted to hold the hooks in an open or closed position, a resilient member having marginal flanges to engage the outer edges of the hookcarrying members, and a member engaging the inner sides of said hook-carrying members. 3. In a device of the character described, a plurality of hook-carrying members adapted to hold the hooks in an open or closed position, a resilient member having slotted marginal flanges which engage the outer edges of the hook-carrying members and permit the hooks to open, and a member engaging the inner sides of said hook-carrying members.

4:. In a device of the character described, a pair of hook-carrying members adapted to hold the hooks in an open or closed position, a resilient member detachably engaging the hook-carrying members and adapted to secure them from accidental movement when the hooks are'in an open or closed position, and a tongue member detachably engaging the adjacent edges of said hook-carrying members.

5. In a device of the character described, a plurality of hook-carrying members adapted to hold the hooks in an open or closed position, a resilient member engaging the hookcarrying members and adapted to secure them from accidental movement When the hooks are in an open or closed position, and amember provided With a plurality of tongues lapping the adjacent portions of said hookcarrying members.

6. In a device of the character described, a plurality'of hook-carrying members adapted to hold the hooks in an open or closed position, a resilient member engaging the hookcarrying members and adapted to secure them from accidental 'movement When the hooks are in an open or closed position, and a member provided With a plurality of alternately-arranged tongues Which engage the adjacent portions of said hook-carrying members.

7. In a device of the character described, a

plurality of hook-carrying members adapted to hold the hooks in an open or closed position, a resilient member engaging the hookcarrying members and adapted to secure them from accidental movement When the hooks are in an open or closed position, and a member provided With a plurality of alternately-arranged tongues flaring at their outer ends and nnderlapping and overlapping the adjacent portions of said hook-carrying members.

8. In a device of the character described, a plurality of hook-carrying members adapted to hold the hooks in an open or closed position, a resilient member overlapping and engaging the hook-carrying members and adapted to secure them from accidental movement when the hooks are in an open or closed position, a member engaging the inner sides of the hook-carrying members, and a strip of suitable material underlying said hook-carrying members and secured to the resilient member, in combination With a suitable cover to which the strip is secured.

In testimony whereof I aflix my signature in the presence of two Witnesses.

WILLIAM P. PITT.
